Hi, it looks like the Cortex M4 core in SMP32MP1 doesn't have flash memory or something like eeprom that can be used as non-volatile memory. Is there any "best practices" to give non-volatile data to the Cortex M4?
Hi,i am trying to understand where and how are RETRAM, MCUSRAM, virtio ring buffer descriptors and virtio buffers allocated. In the next link:https://wiki.st.com/stm32mpu/wiki/Linux_remoteproc_framework_overviewIt is described the device tree configu...
We are a connecting a sensor to M4 side and reading the data through UART7. UART7 is enabled for M4 by modifying the Linux Kernel Device tree and TF-A .dtsi files. Device tree file for TF-A is generated through STM32CubeMX. and Placed the generated f...
Hello, I have a STM32MP157C-DK2 board and I would like to install some packages.But in /etc/apt/sources.list.d there is no sources.list file with repository links to a server.The folder soures.list.d is empty. Where can I get this link to update syst...
I am working on a product. For prototype, I have used Raspberry Pi 3 B+ with Raspbian operating system and firmware in Python 3. For GUI, I used TkInter library. For mass production, I am trying to figure a cost-effective option, and I came across ST...
Hello.recently i get STM32MP1 chips, and i want to use it id devkit with FPGA. But i can't use CUbeMX to get pin definitions, as well as where is no examples that i aware of C code examples, just like with any other chip STM makes. When we get full ...
Hello,Sorry for the basic question, but i have installed the SDK(en.SDK-x86_64-stm32mp1-openstlinux-4.19-thud-mp1-19-02-20.tar), started it as per this article:https://wiki.st.com/stm32mpu/wiki/STM32MP1_Developer_Package#Starting_up_the_SDKI get all ...
Dear Members / ST Employee,I saw :https://hackaday.com/2019/02/27/new-part-day-the-stm32-that-runs-linux/Is there any other variant of STM32 that affordable ?Thanks
I noticed cpufrequtils are installed in the default image. But when you run cpufreq-info you get a message that indicates it is not supported.root@stm32mp1:~# cpufreq-info cpufrequtils 008: cpufreq-info (C) Dominik Brodowski 2004-2009 Report errors a...
